SMT Process Step 1<\/h2>\n\n\n\n

QH3040 high-precision manual stencil printer The same platform as printer can be selectable , easy to locate both single and double sides of PCB board.High flexibility ensure high printing precision.
The steel stencil can be rotated 30 degrees at most , and the precision can be kept all the way when repeat works, can be comparable with automatic machine.
Using the way of steel stencil movement to adjust the best position, combining with the fine adjustment of X-axis Y-axis to correct, convenient and efficient.<\/p>\n\n\n\n

SMT Process Step 2<\/h2>\n\n\n\n

TVM802B SMT pick and place machine (desktop pnp mounter). The advantages of this model are , optimized driver and software algorithm,2 placement heads\uff0c46 slots.
Can handling smallest package size:0402 inch and up to largest size:TQFP100.The external dimensions of TVM802B are 940mm*940mm*320mm. Deluxe edition is mainly composed ofworking head, dual vision system, operation platform, patented feeding rack,, closed-loop motor drive system, internal vacumm pump,etc. Voltage AC220V or AC110V, power 150W.<\/p>\n\n\n\n

  1. QRF320 SMT Reflow Oven solder welding Mixed Process<\/li>\n\n\n\n
  2. Single-sided mixing process: (Plug-in and surface-mount components are on the A side of the PCB) Incoming material inspection -> Solder paste mixing -> PCB A-side silk-screen solder paste -> Patch -> A-side reflow soldering \u2013 > PCB A-side plug-in -> Wave soldering or dip soldering (a small number of plug-ins can be soldered by hand) -> (Cleaning) -> Inspection -> Rework (first post-inserted)<\/li>\n\n\n\n
  3. Double-sided mixing process: (surface mount components on the A side of the PCB, plug-in on the B side of the PCB)<\/li>\n<\/ol>\n\n\n\n

    A. Incoming material inspection -> solder paste mixing -> PCB A-side silk screen solder paste -> patch -> reflow soldering -> PCB B-side plug-in -> wave soldering (a small number of plug-ins can be hand soldered) -> (cleaning )-> Inspection -> Rework<\/p>\n\n\n\n

    B. Incoming material inspection -> PCB A-side silk-screen solder paste -> SMD -> Manual pad on the A side of the PCB pad solder paste -> PCB B-side insert -> Reflow soldering -> (cleaning) \u2013 > Inspection -> Rework (surface mount components on the A and B sides of the PCB, plug-in on either or both sides of the PCB) Surface mount components on both sides of the A and B sides of the double-sided PC<\/p>\n\n\n\n
